Global DNS Servers Parameters
Parameter | Length/Range | Description |
---|---|---|
ednsFailureCount | 1-5 | The maximum number of EDNS failure responses allowed, after which the DNS server is identified as unsupported for EDNS. (default = 3) |
ednsPayloadSize | 512-4096 | The global EDNS payload size, in bytes, for DNS Servers. (default = 1280) |
ednsRetryAfter | 60-180 | The number of seconds to wait before retrying to establish EDNS support after a failure. (default = 180) |
iterationCount | 0-32 | Global DNS iteration count limit for server requests. (default = 8). |
monitoringInterval | 0-300 | Global monitoring interval (in seconds) for DNS Servers. (default = 5). |
probeInterval | 0-300 | Global probe interval (in seconds) for blacklisted DNS Servers. (default = 5). |
retransmissionCount | 0-20 | Global retransmission count limit for DNS iterations of server requests. (default = 2). |
retransmissionTimer | 100-10000 | Global retransmission timer value (in milliseconds) for DNS iterations of server requests. (default = 500) |
| 0-32 | Global number of time outs for blacklisting a DNS Server. (default = 0). |
Use the following command syntax to enable EDNS support (refer to DNS Group - CLI for command details):
